Short answer
For most trips: a fixed-data plan from Nomad — about $17 for 10 GB over 30 days at the promotional price we saw, a named mainland network, hotspot allowed, and the provider stating that blocked apps work without a separate VPN.
If you want unlimited: Airalo, because it is the only provider that publishes what "unlimited" means: 3 GB at high speed every 24 hours, then 1 Mbps. Roughly $27 for 7 days, $49 for 15.
If price decides everything: a specific Trip.com listing has sold 10 GB over 30 days for under $6 — but Trip.com is a marketplace, and the listing next to it can use a different supplier and a different route. Read that section before you buy.
What matters more than the brand: whether the plan routes your traffic internationally. That single line decides whether Google works when you land, and it is buried in the plan terms rather than the headline price.
Why a China eSIM is not like a normal travel eSIM
Everywhere else, an eSIM is a convenience: skip the airport SIM queue, land connected. In China it solves a different problem. Google, Gmail, WhatsApp, Instagram, Facebook, YouTube, X and most Western AI services do not load on a mainland connection — not on a Chinese SIM, not on hotel Wi-Fi, not on a café network. That is the network working as designed.
A travel eSIM roams. Your phone attaches to a Chinese tower as a visiting foreign subscriber, and the data session is handed back to your provider's home network outside mainland China — usually Hong Kong or Singapore — before it reaches the open internet. The filtering is applied to domestic subscriptions, so roaming traffic walks past it as a side effect of how roaming works.
Local SIM: filtered — it is a domestic subscription. VPN: a tunnel out of a filtered network, which can be detected, throttled and blocked. Travel eSIM: ordinary international roaming, no software, no protocol to choose.
The comparison
Seven providers, priced off their own China pages. Read the columns after "price" — that is where the differences that matter actually live.
| Provider | Representative plan | Mainland network | Blocked apps on mobile data | Hotspot | Watch out for |
|---|---|---|---|---|---|
| Nomad | 1 GB/7d $4 · 5 GB/30d $13.50 · 10 GB/30d $17 (sale) · 20 GB/30d $25 (sale) · 50 GB/45d $35 | China Unicom on the plans we read; the wider offering also names China Telecom | Provider states Google, WhatsApp, Facebook, Instagram and X work without an external VPN | Yes | Network can differ between plans — check the checkout card. Buy before you enter mainland China, as Nomad warns purchases can become difficult there. |
| Airalo | Fixed: 5 GB/15d $15 · 10 GB/30d $26.50 · 20 GB/30d $40 Unlimited: 7d $27 · 15d $49 · 30d $69 |
China Unicom | Stated to work with international routing; confirmed by independent testing (see below) | Yes | Fixed-data plans cost more than the cheapest alternatives. Its value is that "unlimited" is defined: 3 GB high speed per 24h, then 1 Mbps. |
| Holafly | Duration-based unlimited: 3d $11.90 · 7d $27.50 · 10d $36.50 · 15d $50.50 · 30d $73.90 | China Mobile | Marketed as reaching Instagram, TikTok and Google Maps. Note: Holafly does not include a VPN, and its China page says so. | Only 1 GB/day | Fair-use speed threshold is not published. The 1 GB/day hotspot cap rules it out for tethering a laptop across a working day. |
| Saily | 1 GB/7d $4.49 · up to 20 GB/30d $39.99; unlimited publishes 5 GB high speed per 24h then ≤1 Mbps | Not publicly named | Sold as an international travel eSIM; routing varies, so verify the current terms | Yes on fixed plans; excessive tethering prohibited | Not the value winner, and the unnamed carrier makes routing harder to check before paying. Install the app before arrival — Saily warns the app may be limited in China. |
| Trip.com (marketplace) | Specific MC SIM listing: 10 GB/30d around $5.70 on a limited-time sale; 7-day and 10-day variants similar | China Mobile on this listing | Listing states ChatGPT support | Yes, with a supplier warning against prolonged heavy tethering | The cheapest and the riskiest. Trip.com is not one eSIM network; two similarly titled listings can have different suppliers, routes, billing clocks and refund rules. Match the supplier and the exact link, and distinguish total data from daily-quota data. |
| Ubigi | 10 GB/30d $17 | China Telecom | Sold as international travel data; verify the apps you need on the current plan | Check the current plan | A straightforward fixed-data product, but less transparent than Nomad or Airalo about blocked-app behaviour on the China plan. |
| Jetpac | Large bundles: 30 GB $29.99 · 40 GB $34.99 on sale; unlimited discloses 3 GB high speed per 24h then up to 1 Mbps | Its own pages conflict between China Unicom alone and China Unicom plus China Telecom | Verify on the exact plan | Check the current plan | Good price per gigabyte, unclear terms. Treat as a high-data alternative after checking the specific plan, not as a default. |
Prices read from each provider's China page in August–September 2026. Promotional pricing rotates weekly; the number you see at checkout is the one that counts.
What "works without a VPN" actually means
Provider pages use this phrase freely, and it is the single most misunderstood claim in this category. Two different things are being described:
- International routing — your data exits through the provider's home network abroad. Blocked apps work because the traffic never passes through the mainland filter. This is a property of the plan, not the brand, and some providers offer it on some products and not others.
- A built-in VPN — an encrypted tunnel inside the connection. Most travel eSIMs do not include one, and at least one major provider says explicitly that it does not.
So the useful question is never "does this brand bypass the firewall?" It is "does this specific plan route internationally?" Marketplaces make that harder: the same storefront can list plans with completely different suppliers underneath.
Independent testing, and where it disagrees with the spec sheets
We have not run controlled speed tests, so rather than inventing a winner we point at the testing that exists. One independent reviewer used eleven providers on real trips through Beijing, Xi’an, Chengdu, Guangzhou, Shanghai, Tibet, rural stretches and high-speed rail, and reported that Nomad, Airalo, Yesim and SIM Local reached Western apps on mobile data without a separate VPN on the plans tested. Their conclusion was not about peak speed but about recovery: which provider reconnects fastest after a tunnel drops the signal.
That is a single tester’s experience on specific plans on specific dates, which is exactly the level of evidence this category allows. A second guide covering the same providers chose to compare published terms only and explicitly declined to name a fastest provider. We take the same position: the spec sheet tells you the price and the routing, and the road tells you the rest.
Choosing by trip type
| Your trip | What to prioritise | Sensible pick |
|---|---|---|
| 5–10 days, two or three big cities | Simple fixed data, low price, no throttling surprises | A Nomad fixed plan, or Airalo if you would rather not count gigabytes |
| Multi-city with high-speed rail, or Tibet and rural stretches | Reconnection after signal loss, and network coverage outside cities | Providers naming Unicom and Telecom on the plan, or a regional Asia plan |
| Working remotely, laptop on hotel Wi-Fi | Hotspot allowance and a VPN as a second route | A fixed plan with unrestricted hotspot, plus a VPN for the laptop — see the VPN guide |
| Family or group | One plan per device, not one plan shared | Separate eSIMs; hotspot caps make sharing unreliable |
| China plus Hong Kong, Macau or Japan | A regional plan instead of a China-only one | Regional Asia products, and note that Hong Kong and Macau are outside the mainland filtering regime anyway |
| You need a +86 phone number | A travel eSIM will not give you one | A passport-registered physical SIM, bought in China |
About Chinese carrier eSIMs
Articles written before October 2025 still say mainland China has no phone eSIM. That is out of date: China Mobile, China Unicom and China Telecom began nationwide commercial phone-eSIM trials on 13–14 October 2025. It does not change the practical answer for visitors. Activation, transfer and conversion require an approved mainland-market device, a carrier-owned store and in-person identity verification, and Apple’s current guidance lists only mainland-market models for mainland carrier eSIM. A phone bought abroad can run a travel eSIM perfectly and still be unable to install a domestic Chinese profile. A mainland carrier line is also a domestic subscription, so it does not route around the filter.
What it costs, against the alternatives
| Option | Typical cost for a two-week trip | Blocked apps? | Effort |
|---|---|---|---|
| Travel eSIM (fixed data) | $15–30 | Work if the plan routes internationally | Buy and install before you fly |
| Travel eSIM (unlimited) | $45–55 for 15 days | Same | Same |
| Local physical SIM | $10–25 | No — it is a domestic line | Passport registration, a carrier shop, and not every branch handles foreign documents |
| Home carrier roaming pass | $5–15 per day | Usually works, since roaming is roaming | Nothing to install |
| Pocket Wi-Fi | $40–80 plus deposit | Depends on the unit’s routing | Pick up and return a device; useful for a group |
The comparison that surprises people is the second row against the fourth: two weeks on a home-carrier daily pass can cost several times the whole eSIM. The one real advantage of roaming on your home SIM is that it already includes international routing — if you are on a generous plan, check what your carrier charges before buying anything else.
Setting it up, in order
The order matters more than the list. Everything here has to happen while your home network and app store still work normally.
- Check the phone is unlocked and eSIM-capableConfirm the exact model appears in the provider’s compatibility list. A carrier-locked handset cannot use any of these plans.
- Confirm the plan routes internationallyLook for international routing, roaming, or a Hong Kong or Singapore exit point. This is the line that decides whether Google works.
- Read the allowance, the throttle and the hotspot rule"Unlimited" usually means a high-speed daily allowance then a slow tier. If you plan to tether, check the cap before you commit.
- Buy and install it at homeNot at the airport, and not after landing. Installation needs a data connection and provider pages are themselves blocked in China.
- Do not activate it earlyMost plans start counting from activation, not purchase. Some start on installation — read which one applies.
- Save the details somewhere that is not the appQR code, manual activation details, APN, order number, and a support contact reachable by email or web chat. If the app is slow in China, you want a route that does not depend on it.
- Label the two linesName them "Home" and "China", then select the China line for cellular data. Turn data roaming on for the travel eSIM and leave the home line’s data roaming off.
- Decide what the home line is forKeeping it active for SMS verification codes is usually worthwhile. Check what your carrier charges for receiving them while roaming.
- Download the essentialsOffline maps, translation, Alipay or WeChat Pay, and the apps you will need in China — installed and logged in while you still can.
Signal but no internet: working through it
Signal bars prove the phone can see a tower. They prove nothing about the data line, the roaming setting, the package or the APN. Work down this list in order before assuming the plan is broken.
- Confirm the travel line is switched on.
- Confirm it is the line selected for cellular data.
- Turn data roaming on for the travel eSIM, not the home line.
- Toggle airplane mode, then restart the phone.
- Compare the APN with the instructions you saved. There is no safe universal "China APN".
- Leave network selection on automatic first; only try named networks manually if the provider lists them.
- Check whether the package has started, expired, hit a daily quota or reached its high-speed cap.
- Contact support by the saved route — without deleting the eSIM. Some profiles install only once, and a replacement can need support access that is harder to reach after landing.
One specific case worth recognising: if blocked apps work on the eSIM but stop when your phone joins hotel, airport or station Wi-Fi, nothing is broken. Mainland Wi-Fi stays behind the firewall even when the roaming line beside it does not. Switch Wi-Fi off and carry on.
Do you still need a VPN?
For your phone, usually not — that is the point of the eSIM. A VPN becomes necessary in one situation: a laptop on hotel Wi-Fi, which the eSIM cannot cover because it only serves the device it is installed in. Tethering can substitute, but check your plan’s hotspot cap first; several limit it to 1 GB a day.
If you do carry a laptop, treat the VPN as a backup rather than a plan. Standard WireGuard, OpenVPN and IKEv2 were detected and blocked on mainland networks in 2026, and reliability moved again during the April 2026 crackdown. The VPN guide for China covers which modes still connect and why no brand can promise it.
Frequently asked questions
Which eSIM is best for China in 2026?
On published terms, a fixed-data Nomad plan is the sensible default for most trips: roughly $17 for 10 GB over 30 days at the promotional price we saw, a named mainland network, hotspot allowed, and the provider stating blocked apps work without a separate VPN. Airalo is the clearest unlimited option because it publishes its throttle. Trip.com listings can be cheapest but routing varies between listings.
Does a travel eSIM really bypass the Great Firewall?
Yes, as a consequence of roaming — but only if the plan routes internationally. Your data is handed to the provider's home network outside mainland China before it reaches the open internet. Some plans break out locally through the mainland network and leave you behind the firewall regardless of the plan page's marketing.
Can I use Google Maps and WhatsApp in China?
Yes, on mobile data routed internationally. On a Chinese SIM, hotel Wi-Fi or any mainland breakout connection they will not load. Amap (Gaode) is the local alternative, with an English interface and offline maps.
Is a Chinese carrier eSIM an option for tourists?
Not practically. China's three carriers opened phone-eSIM commercial trials in October 2025, but activation requires an approved mainland-market device, a carrier-owned store and in-person identity verification. A phone bought abroad can run a travel eSIM perfectly and still be unable to install a domestic Chinese profile.
How much data do I need for a trip to China?
Navigation, messaging, payments and translation use roughly 1–2 GB a week. Add more if you upload photos, work remotely or stream video. Two travellers should buy separate plans rather than sharing a hotspot, because several providers cap hotspot use at 1 GB per day.
How far in advance should I buy a China eSIM?
Days, not minutes. Buy and install while you still have unrestricted internet and can receive email — provider sites and app stores are themselves blocked on mainland networks, and activation needs a working connection. Do not activate early if validity starts at activation.
Can I install a China eSIM after landing?
Technically the profile installs, but it is the worst moment to try. You need your provider's app or portal, which may be slow or unreachable, plus payment and email access to fix anything that fails. Install before departure.
Will my home SIM still receive verification codes?
Usually yes if you leave it active with roaming enabled, though some carriers charge for it. Alipay and WeChat verify accounts by SMS. Keep the home line on for texts and route data through the eSIM.
Why does my eSIM show signal but no internet?
Signal bars only prove the phone sees a network. Confirm the travel line is on and selected for data, turn data roaming on for that line only, toggle airplane mode, restart the phone, check the APN against your provider's instructions, then check whether the plan has started, expired or hit a daily cap. Do not delete the eSIM while troubleshooting — some profiles install only once.
Is a China eSIM cheaper than international roaming?
Almost always, often by a wide margin. Typical home-carrier roaming passes run $5–15 a day, while a fixed-data China plan covering two weeks costs roughly $15–30. The eSIM also gives you the international routing that not every roaming add-on includes.
Do I still need a VPN if I have an eSIM?
For your phone, usually no. A VPN is still worth having for a laptop on hotel Wi-Fi, because a travel eSIM only serves the device it is installed in and tethering may be capped.
Do I need a Chinese phone number?
For an ordinary trip, no. Payments, transport and attraction bookings all work without one. You need a mainland +86 number only for things like receiving local delivery calls or registering a business account, and that means a passport-registered physical SIM rather than a travel eSIM.
